Abstract
A boundary value problem on a nanometer hole in an elastic plane under arbitrary remote loading is solved. It is assumed that complementary surface stress is acting at the boundary of the hole. The outer surface of the hole is supposed to be conformally mapped on the outer surface of the circle by means of a power function. The Gurtin–Murdoch surface elasticity model is applied to take into account the surface stress effect. Based on the Goursat–Kolosov complex potentials and Muskhelishvili’s technique, the solution of the problem is reduced to a singular integro-differential equation in an unknown surface stress. For a nearly circular hole, the boundary perturbation method is used that leads to successive solutions of hypersingular integral equations. Numerical results based on the first-order approximate solution are specified for an elliptical nearly circular hole.
